Looking back at the op in my "Exit tabs & gore signage" thread, something I noticed is that the exit arrow for
Missouri and
Ohio's BGS are more slanted towards the bottom right than the exit arrow for the
Minnesota BGS (all three use the same exit tab, and are the first 3 images in that thread, which is why I'm using them as examples). I don't know the exact angles for those arrows, but looking at the images in that thread, I'm guessing it's 45° for MO and OH, and 60° for MN, for exit arrows for a right exit (let me know if the angles are different values). The same seem to apply for gore signs in each state.
Which angle is used in your state, and which angle do you prefer? For me, I like the 45° exit arrow angle better, maybe it's because I'm mroe used to seeing them over 60°. Also, I've seen a 30° exit arrow before, but forgot which state it's in, so it'll be a category below, but blank for now. Incomplete list of states below:
States that use 30° right exit/150° left exit arrow angleStates that use 45° right exit/135° left exit arrow angle- Illinois
- Indiana
- Kentucky
- Missouri
- Ohio
- Wisconsin
States that use 60° right exit/120° left exit arrow angle- Michigan
- Minnesota
